In Austria 6 Claims.

This invention relates to improvements in securing the joint ofsuperposed reenforcement skeletons for use in connection with ferroorsteel concrete columns. The joint is secured by an independent memberwhich I refer to hereinafter as a special reenforcement which isprovided to secure the continuity of the hooping. The object of thearrangement of these special reenforcements is to prevent aninterruption of the hooping at the joint, the special reenforcementbeing used for reenforcement skeletons of any kind and shape, e. g. castiron cores as well as longitudinal reenforcement bars or rods of anycross sectional area. The binding members may consist either of aspecial wire hooping or of a pipe.

Some modes of carrying out the present invention are illustrated by wayof example in the accompanying drawings, in which:-

Figure 1 is a substantially longitudinal sectional view of my improvedreenforcement unit; Figure 2 is a substantially transverse sectionalView of the same.

Fig. 3 is a perspective view of the invention on an enlarged scale.

Figure 4 is a substantially longitudinal sectional view of amodification; Figure 5 is a substantially longitudinal transversesectional View of the modication illustrated in Figure 4; vand Fig'-ures 6 and 7 are perspective views thereof in different stages ofassembly.

Referring to the drawings and particularly to Figures 1, 2 and 3, 1denotes each-of four spaced longitudinal reenforcement bars or rodswhich are provided with distancing members 2 and eyes 3, the latterserving as means for holding inverted L-shaped joint guards 4 rigid onthe rods 1. U-shaped brackets 5 are attached to the shorter arms of theguards 4 and embrace channel molds 9 transversely thereof. Embracing thebars 1 above and below the molds 9, respectively, are spiral reenforcinghooping members 6 and '7, the latter forming the top and bottom skeletonframes. Overlapping the abutting ends of the hooping members 6 and 7 isa sleeve comprising a wire coil 8 which is large enough in diameter tonot only embrace the ends of coils 6 and '7 but the upright portions ofthe guards 4 as well.

In the construction shown in Figures 4 to 7, I support the molds 9 bymeans of a tubular distancing member 10 which is welded to thelongitudinal reenforcement rods or bars 1 about the inner sides thereof.Connecting members 1l carried by and projecting radially of the tube 10,support a tubular binding sleeve 12 which em- April 4, 1930 (Cl. 'l2-76)braces the rods 1, as iuustrated in Figure 5, and C' is spaced from thetube 10 to form a mold for the cement lling at the joint. Plate 14supports from below, the beam-channels 9, the plate 14 being welded tothe tubular binding sleeve 12 atv the lower end thereof.

The individual parts may be connected in any other convenient way forinstance by screws, rivets and the like.

According to Figures 6 and '7 the rods 1 are held in spaced relation bymeans of tubular sections 15, which are arranged on the inner sides ofthe rods and in practice, aord substantial reenforcement for the column.

Figures 6 and 7, show the manner in which the column head is assembledat the floor or ceiling joint.

I claim:-

l. Reenforcement for concrete columns comprising superposedreenforcement skeletons, a sleeve for the joint of abutting skeletons, aplate secured to said sleeve, a beam-channel xed to said plate, adistancing tube within said sleeve and overlapping the said joint, andconnecting members secured to said distancing tube and to said sleeve.

2. In a reenforcing core for concrete columns, the combination ofsections of spaced rods abutting each other at their ends to form ajoint, inner sleeves disposed intermediate the sections and ati' pointsof connection of said girders on said rods,'.`4

said second embracing means being independent of said rst embracingmeans to overbridge the space unembraced by the latter.

4. In a reenforcing corerfor concrete columns,

the combination of superimposed units consisting,

of spaced rods, adjacent ends of said units abutting each other to formjoints, sleeves embracing the rods at the joints, and tubular sectionsintermediate the length of the rods and disposed interiorly of the coreformed by the rods to reen-` force the same between the joints.

5. In a reenforcing core for concrete columns, the combination ofsuperimposed units consisting of spaced rods adjacent ends of said unitsabutting each other to form joints, sleeves embracing, llo

abutting the ends of the bars of the next unit to form a joint, a sleeveembracing the bars at each joint, wire coils positioned upon andembracing the rods, said interconnected units of rigid bars forming oneself-supporting unit extending throughout the height of a building.
